Palin endorses Rick Perry in TX

From NBC's Mark MurrayThis endorsement will endear Palin to conservatives. But could it undermine a potential 2011/2012 message about women breaking barriers in politics? And what does it say about her trying to shore up her weaknesses with independents and the political middle?

"Palin, who electrified the GOP base as the party's vice presidential nominee last year, has strong support among the party's social conservatives. Her endorsement appeared aimed at undercutting Hutchison's appeal with GOP women. Both groups will be important in picking the party's nominee in next year's GOP primary."
